Question

electronic configuration of cl35 and cl 37 with their symbol​

Answer 1

Both are Isotopes of Chlorine with different mass number due to different number of neutrons but same number of protons. Thus both the atoms have same number of electrons.

Both are Isotopes of Chlorine with different mass number due to different number of neutrons but same number of protons. Thus both the atoms have same number of electrons.The atomic number of Chlorine is 17 hence the electronic configuration is (2, 8, 7). Thus both the atoms have -1 valency as it would have to gain 1 electron and make the outermost shell with 8 electrons to achieve stability as per the Octet rule.
